Abstract: In a general aspect, a system for generating radio frequency (RF) electromagnetic radiation includes a maser having a photonic crystal structure and a vapor. The photonic crystal structure is formed of dielectric material and includes an array of cavities having a defect region disposed therein and an elongated slot disposed in the defect region. The array of cavities and the elongated slot define a waveguide having a waveguide mode. The vapor is disposed in the elongated slot and includes one or more input electronic transitions and an output electronic transition coupled to the one or more input electronic transitions. The output electronic transition is operable to emit a target RF electromagnetic radiation and is resonant with the waveguide mode. The system also includes a laser system configured to provide input optical signals to the elongated slot and signal processing electronics in communication with the laser system.

Abstract: In a general aspect, a receiver is disclosed for sensing radio frequency (RF) electromagnetic radiation. The receiver includes a dielectric body having an array of cavities ordered periodically to define a photonic crystal structure in the dielectric body. The dielectric body also has a region in the array of cavities that defines a defect in the photonic crystal structure. An elongated slot through the region extends from a slot opening in a surface of the dielectric body at least partially through the dielectric body. The receiver also includes a vapor or a source of the vapor in the elongated slot as well as an optical window covering the elongated slot. The optical window has a window surface bonded to the surface of the dielectric body to form a seal about the slot opening.

Abstract: In a general aspect, a method of manufacturing a vapor cell is presented. The method includes obtaining a dielectric body having a surface that defines an opening to a cavity in the dielectric body. The method also includes obtaining an optical window that includes a surface. The surfaces of the dielectric body and the optical window are altered to include, respectively, a first plurality of hydroxyl ligands and a second plurality of hydroxyl ligands. The method additionally includes disposing a vapor, or a source of the vapor, into the cavity. The altered surface of the dielectric body is contacted to the altered surface of the optical window to form a seal around the opening to the cavity. The seal includes metal-oxygen bonds formed by reacting the first plurality of hydroxyl ligands with the second plurality of hydroxyl ligands during contact of the altered surfaces.
